I have my TSH level 2.320. My general practioner doctor said it doesn't matter about the T3 or T4 as long as we have enough of a level the brain doesn't care or something like that. I had some other thyroid test done by my gyno a couple months ago and have called to request that test hoping maybe he did a t3 t4 test. I had my
t3 t4 a couple years ago by this gyno and my T-3 was 1.37 and the free t4 was 0.9. But didn't notice a TSH number. In the past a couple years ago when I got total TSH from the general practioner was usually 1.17 one time and 1.57 another time. The thing is I have recently found out I have very low Vitamin D also have low B-12 caused by pernious anemia. The D is low I suppose because I very rarely get in the sun. My doctor did tell me that vitamin D is actually a hormone and not a vitamin I thought that was interesting. I know the reference range has been changed for thyroid online but the doctors don't go by it on my test it shows .450 to 4.50. Not really asking so much as just wondering about this the tsh number going up. thanks LindaM

So many doctors are still living in the dark ages by using TSH only to diagnose thyroid disease.

You didn't mention if you have hypo symptoms or not, do you?

The only real way to diagnose is to run a Free T3 and Free T4 (the FREE part is important to include). You should also be screened for thyroid antibodies, TPO-Ab and TG-Ab. Only with these tests will you be effectivly screened for thyroid disease.

When you post your lab results, you need to post the ranges that go with them as they differ from lab to lab. But other than the Free T3 and Free T4 and the antibody tests, the rest are pretty useless.
